Available in PDF, EPUB and Kindle. Book excerpt: This factsheet provides information about sources and effects of the pollutants that threaten British Columbia's fragile marine environments. In particular, it looks at the persistent pollutants that are the object of much research, and describes some of the steps that governments and industries are taking to better control pollution. It summarizes information presented in the first state of the environment report, which included data for 1970-86, and supplements it with data for 1986-88.

Download or read book Sewage Pollution in British Columbia in Perspective written by Michael Waldichuk and published by . This book was released on 1984 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The historical development of sewage disposal, in the context of its effect on the environment, is briefly reviewed. The characteristics of sewage, i.e., solids, microorganisms, dissolved organic constituents, nutrients and metals, that affect the aquatic environment and ecosystem are discussed. A brief review is given of the three levels of treatment: primary, secondary and tertiary. Then four case studies of sewage treatment and ocean disposal in coastal areas of British Columbia (Greater Vancouver, Greater Victoria, Comox-Courtenay, and Nanaimo) are reviewed in some detail. Other areas are discussed with respect to specific problems. The perceived problems are largely associated with the impact of sewage bacteria and viruses on shellfish and the potential hazard to consumers. Closure of shellfish beds to harvesting, because of sewage pollution, has had a major economic impact.

Download or read book Bioaccumulation of Pollutants in Galapagos Sea Lions and Marine Mammals from British Columbia Canada written by Juan José Alava and published by . This book was released on 2011 with total page 906 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioaccumulation is a key criterion to assess and manage commercial chemicals and pollutants recognized internationally in the United Nations Stockholm Convention for Persistent Organic Pollutants, the Registration, Evaluation, Authorization and Restriction of Chemicals Program in the European Union, the Toxic Substances Control Act in the USA and nationally the Canadian Environmental Protection Act. Bioaccumulation is the process by which chemical concentrations achieve high levels in wildlife and humans, which can cause health effects and elevated health risks. To assess the degree of bioaccumulation and health effects of persistent organic pollutants in marine mammals, field studies of the bioaccumulation and health effects of these pollutants were conducted in a remote marine environment (Galapagos Islands, Ecuador) and in local marine ecosystems of British Columbia, Canada. The main findings of this work indicate that a number of persistent organic pollutants, including PCBs, DDTs and several other organochlorine pesticides biomagnify in Galapagos sea lions but are generally below concentrations associated with known effects. An increase in DDT concentrations was observed in Galapagos sea lions from 2005 to 2008, which may be related to the renewed use of DDT in malaria affected regions endorsed by the World Health Organization in 2006. PCB and PBDE concentrations were higher in Steller sea lions than in Galapagos sea lions. PCBs in Steller sea lions exceeded immunotoxic and endocrine disruption thresholds. To provide science-based tools for the management of pollutants, a bioaccumulation model for marine mammals was developed and tested. The model was applied to derive sediment target values for sediment remediation and for the derivation of ocean disposal permits in British Columbia. The application of the model shows that current sediment quality guidelines in Canada are not protective of the health of killer whales and Steller sea lions. Based on the model results, I recommend values that can be used as a basis for the derivation of sediment quality criteria for the protection of marine mammals in British Columbia. The findings support environmental management plans to mitigate chemical stressors of marine mammalian ecosystems in the Galapagos Islands and British Columbia.

Download or read book An Assessment of Polybrominated Diphenyl Ethers PBDEs in Sediments and Bivalves of the U S Coastal Zone written by K. L. Kimbrough and published by . This book was released on 2009 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report represents the first national assessment of PBDEs in the U.S. coastal zone. Results suggest that they are widely distributed nationally. Several regions, including the northern Mid-Atlantic, central Gulf of Mexico, Southern California, Pacific Northwest and the Great lakes have elevated PBDE concentrations compared with other coastal regions. Furthermore, PBDE concentrations are positively correlated with human population density along the U.S. coastline. The national and regional perspectives provided herein are intended to support research, local monitoring, and to assist resource managers and policy makers tasked with making regulatory decisions about these contaminants.
